Monitor or Projector Says "No Signal"

Typically this is cause by a change in display settings, to fix this, press the "Windows" key and "P" on the keyboard to bring up this menu:

Select "duplicate" to display the same image on the screens. Select "extend" to use the screen as an extension of the main screen. Most users will use "duplicate."

If this doesn't correct the problem, check that the cables from the PC to the screen are secure. If you use a laptop with a docking station, disconnect power to the docking station, wait 5 seconds and reconnect power. If these steps do not correct the issue, you can submit a work order.
